Required: Distance between main beams and between supports
Available: 24 cm concrete thickness with total load of 8.24 kN/m 2
Selected: Distance between crossbeams of 0.625 m
Result: 1.98 m distance between main beams
(select next larger distance between main beams, here 2 m)
1.02 m distance between supports (check carrying capacity of supports)
